6 Claims.

This invention relates generally to hay rakes, tedders and the like andis more particularly concerned' with the reel structure usuallyincorporated in an apparatus of this type.

And the present invention is directed toward and has as an object theprovision of a reel structure incorporating features of improvement asto construction and mounting affording a material reduction in the time,effort and skill required to assemble or disassemble same.

Another object and feature of this invention is the provision of a reelstructure utilizing interchangeable parts and detachable reel-barbearing mountings permitting these bars to be separately removed andreplaced or serviced, as required.

Still another object of this invention is the provision :of a reelstructure incorporating improved features of construction for reel barshavin crank extensions adapted to be journaled in peripheral bearingportions of a spider element whereby the reel bars may be assembled onthe reel structure either before or after the spider element has beenoperativelymounted thereon;

A further object of this invention is to provide a durable reelstructure incorporating features of simplification as to constructionand assembly affording material advantages as to cost of manufacture andmaintenance.

The construction, assembly and operation of apparatus embodying theinvention will become readily apparent as the disclosure progresses andparticularly points out additional objects and advantages considered ofspecial importance. And accordingly,'the present invention may beconsidered as comprising constructions, combinations and subcombinationsof elements, including parts thereof, as is hereafter more fully setforth in the detailed description and appended claims. And for a betterunderstanding of the construction, assembl and operation of anillustrative app-aratus, attention is directed to the accompanyingdrawing illustrating but one embodiment of the invention and in which:

Fig. 1 is a plan view of a rake reel assembly and mounting with certainparts omitted in the interest of simplicity;

Fig. 2 is a view in elevation of the left end of the structure shown inFig. 1;

Fig. 3 is a view in elevation of the right end of the structure shown inFig. 1 with parts omitted in the interest of simplicity; and

Fig. 4 is an enlarged longitudinal vertical section through the rightend of the reel assembly shown in Fig. 1 with parts further cut away tobetter show the construction.

As best seen in Figs. 1, 2 and 3, the reel mounting frame structurecomprises parallel front and rear side members I and 2, respectively,having their left hand end portions interconnected by a bar 3, havingtheright hand end portions connected by an angle member 4 and havinglongitudinally spaced opposed portions interconnected by bracket formingstripper bars 6. This frame structure also includes a rigid beam I whichhas its rearend fixedy secured to a plate 8 attached in bracing relationto the rear left hand corner ofthe frame structure and which extendsfor- -wardly over the frame structure in upwardly arched obliquerelation thereto. The mid portion of the front and rear frame membersare interconnected by an upwardly arched brace 9 having its forward endattached to member I in underlying relation with respect to beam I. Afor- .wardly projecting beam II has its rear end fixedly secured to aright hand extension of member 2 and extends forwardly therefrom beneathfront member I in spaced underlying relation thereto. Angle member 4also extends forwardly beneath member I in underlying spaced relationthereto and is secured therewith by means of a spacer tube I2 throughwhich passes the adjacent end of a basket forming bar 6, the latterhaving a threaded end portion which passes through an aligned aperturein front member 5 and is fixed thereto by means of a nut I 3. Theforwardly extending beam I I may also be secur d to the overlyingportion of member I in substantially the same manner as just describedwith respect to angle member d. The left side of the reel frame includesa, U-shaped bearing supporting bracket I 4 secured in depending relationto the mid portion of bar 3, the latter being braced by a member M5connecting an intermediate portion thereof with a portion of beam Ispaced from plate 8 and rear member 2. The right side of the reel framealso includes a U-shaped bearing support bracket H (see Fig. 3) securedin depending relation to a portion of angle member 13 intermediate itspoint of connection with front and rear side frame members I and 2. Abrace member I5 connects the reel bearing supporting portion of anglemember 4 with an opposed portion of beam II. The frame structure justdescribed is adapted to be supported in part by a pair of ground engagedwheels (not shown) and in part by a forwardly extending draft structure(not shown) including as elements thereof the forwardly converging beammembers I and II.

A pair of opposed reel stub shafts I8 and I9 are rotatably mounted inbearings ZI and 22, re-

mounting disc '31 to turn-relative thereto.

spectively, including rectangular housing structures having groovedopposite sides guidedly engaged with the inner opposed edges of U-shapedbrackets l4 and I1, respectively. These bearing structures are suspendedfor vertical adjustment relative to brackets l4 and I! by means ofchains, cables, orthetlike, 23 :andid which, pass over suitable .framemounted pulleys or equivalent guiding elements 26 and 21, respectively,and are adapted to be connected with a suitable COI1VBI1-. tionaladjusting means such as levers or the like (not shown). The oppositeends of stub shafts t8 and I 9 are united and in effect made continuousby an interconnecting.tubeshaftQZS fixedly secured in telescopingrelation to. the opposite:

ends of these stub shafts in any suitable manner such as by pins, capscrews or the liken-as shown in Fig. 4. The portion of stub shaftIBMadjacent bearing '2 I, the mid portion of tube shaft 29, and

the portion of stub shaft 19 adjacent bearing 22 each has .a similarreel-bar supporting disc 3| keyed or otherwise secured --thereto,these'discs each presenting a peripheral fiange 32 generally parallel tothe axis of shaft'ZB. A plurality of similartine carrying reel bars 33are detachably secured to the-outer peripheral surfaces of flanges I32in,circumferentially spaced'relation with respect to each 'other by'means of similar bearing and: strap elements-34 and 36; respectively.As shown reel bar 33 comprises 'a pair-of-tubular members 25 and 3!!secured irrtelescoping relation to opposite'endsof a 'stub shaft-35inany suitable manner such as--described infrelation to stub shafts, l8and" L9. The left ends of each tubular member 25 are-secured intelescoping relation to a stub-shaft 45 in a conventionalmanner and theright ends of each tubularmember 39 are likewise secured'toacrank-extension 39. The left end, the'rightendand the midportion ofeach reel bar 33, that 'isstubshafts '45, 35" and crank senting adepending positioning boss adapted to i be inserted in a hole 31 in discflange 32.
